University of Wisconsin-Madison researchers have announced a significant step forward in the development of materials that can ward off oil — a discovery that could lead to new protective coatings and better approaches to cleaning up oil spills. In a new paper in the journal Advanced Functional Materials, professor of chemical and biological engineering David Lynn and assistant scientist Uttam Manna describe new coatings that are extremely oil-repellant (or "superoleophobic") in underwater environments.

Japan's latest plans for 'scientific whaling' in the Southern Ocean have fallen at the first hurdle, writes Tony Press. The IWC's expert panel says Japan's proposal contains 'insufficient information' on which to judge its validity, in particular the need for the 'lethal sampling' of over 3,996 Minke whales that is central to the research plan.

Consumers whose drinking water can be contaminated by the release of untreated wastewater after heavy rains face increased risk for gastrointestinal illness, according to a report in the journal Environmental Health Perspectives. “Combined” sewer systems collect both sewage and stormwater runoff on the way to treatment facilities. When heavy rainfall fills these systems beyond their capacity, untreated wastewater can back up into homes. To reduce the risk of home flooding during heavy precipitation, municipalities often discharge some of the untreated flow into nearby bodies of water. The release of untreated waste is known as a combined sewer overflow.

The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.

There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.

Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.

Do you have any idea just how many organizims are in seawater?  Not the fish you can see, but the microscopic organizims you cant see?

Dip a beaker into any portion of the world’s oceans, and you’re likely to pull up a swirling mix of planktonic inhabitants. The oceans are teeming with more than 5,000 species of phytoplankton — microscopic plants in a kaleidoscope of shapes and sizes. Together, phytoplankton anchor the ocean’s food chain, supplying nutrients to everything from single-celled organisms on up to fish and whales.

Through photosynthesis, these tiny organisms supply more than half the world’s oxygen. When these plants die, they drift to the ocean bottom, or evaporate into the air as carbon — a process that generates more than half the world’s cycling carbon.

Every child's ability to succeed in school is influenced by lots of external factors: teacher quality, parenting, poverty, geography, to name a few. But far less attention has been paid to the power of a child's bedroom walls. Or, rather, the paint that's on them and the lead that may be in that paint. A new study published in the Harvard Educational Review suggests that efforts to reduce kids' lead exposure have led to tangible academic gains in Massachusetts.
